Wires play a key role in power transmission, signal transmission, lighting fixtures, control circuits, and traffic lights. They are widely used in modern life and are an indispensable infrastructure. As an important part of electrical appliances, wires can transmit electrical energy to various terminal devices or homes and industrial premises, and transmit this electrical energy to various electrical equipment.

[0003] At present, a Chinese utility model patent with a publication date of July 16, 2022 and a publication number of CN217740221U discloses a structurally stable single-core soft conductor cable, which includes a battery core, the outer coating of the battery core is provided with an insulating layer, the outer coating of the insulating layer is provided with a shielding layer, the outer coating of the shielding layer is provided with a buffer layer, and the outer coating of the buffer layer is provided with a wear-resistant jacket. The beneficial effects of the utility model are: the buffer layer is used to buffer and dissipate energy, thereby avoiding structural deformation of the battery core after being squeezed, thereby improving the stability of the cable structure; when the cable is squeezed, the staggered second protrusions and the first protrusions are squeezed, and since there is a certain cavity between the staggered second protrusions and the first protrusions, the first buffer sleeve and the second buffer sleeve have a large deformation amount, thereby improving the overall buffering effect of the buffer layer, further avoiding structural deformation of the battery core after being squeezed, thereby further improving the stability of the cable structure.

[0004] However, since soft-core wires are made of multiple thin copper wires, when users insert and pull the wires into the wire tube, they may be squeezed or stretched by the outside world, which may cause the wires to break or break. Utility Model Content

This design can be both shock-resistant and wear-resistant, and is not prone to large deformation. At the same time, the cavity formed between the first support layer and the second support layer also increases the anti-extrusion performance and buffering performance of the wire.

[0029] Wires are conductors that conduct electric current. They consist of one or more conductors and are covered with a protective layer. Wires play a key role in power transmission, signal transmission, lighting fixtures, control circuits, and traffic lights. They are widely used in modern life and are an indispensable infrastructure. As an important part of electrical appliances, wires can transmit electrical energy to various terminal devices or homes and industrial premises, and transmit this electrical energy to various electrical equipment.

[0030] The single-core soft conductor cable in the related technology is made of multiple thin copper wires, and the soft core wire is very soft. Its bending radius is smaller than that of the hard wire, and it is easily limited by tension and extrusion force. When the user inserts and pulls the wire into the wire tube, it encounters external extrusion force and excessive tensile force, which may affect the single-core soft conductor wire, causing the circuit to break or break, thereby causing disconnection problems and safety hazards.

[0031] Based on this, in order to improve the technical problem that the soft conductor in the related art is easily broken or damaged by external tension and extrusion, the embodiment of the present application provides the following solution:

[0032] Please also read Figure 1 and Figure 2The embodiment of the present application provides an anti-extrusion single-core soft conductor wire, including a conductor core 100. A braided shielding layer 200 is arranged on the outside of the conductor core 100, an insulating layer 300 is arranged on the outer layer of the braided shielding layer 200, a support assembly 400 is arranged on the outer side of the insulating layer 300, and the support assembly 400 includes a first support layer 410, a second support layer 420 and a plurality of support blocks 430, the first support layer 410 is closely arranged on the outer surface of the insulating layer 300, a second support layer 420 is equidistantly arranged on the outer side of the first support layer 410, a plurality of support blocks 430 are arranged in an array between the first support layer 410 and the second support layer 420, and a plurality of cavities 440 are evenly opened between the support blocks 430 and the first support layer 410 and the second support layer 420.

[0033] As can be seen from the above, the embodiment of the present application provides an anti-extrusion single-core soft conductor wire. When the wire is used, power and signal transmission can be achieved through the conductor core 100. The braided shielding layer arranged on the outer layer of the conductor can reduce electromagnetic interference and improve signal quality. In addition, the braided shielding layer can also play a heat dissipation role, helping the wire to maintain good performance in a high temperature environment. The insulating layer 300 arranged at the outer end of the braided shielding layer can electrically isolate the conductor core 100 from the earth and other wires, ensure the transmission of power and prevent people from being injured by electric shock. The first support layer 410, the second support layer 420, and the support block 430 are fixedly connected. The first support layer 410 and the second support layer 420 are made of hard plastic materials and both adopt a closed structure. When subjected to external compression and stretching, the second support layer 420 near the outer end can evenly transmit the force received to the first support layer 410 through the support block 430, and has good stability, which can well protect the inner conductor core 100 and reduce the occurrence of breakage and damage. This design is shock-resistant and wear-resistant, and is not prone to large deformation. At the same time, the cavity 440 formed between the first supporting layer 410 and the second supporting layer 420 also increases the anti-extrusion performance and buffering performance of the wire.

[0034] See also Figure 1 to Figure 2 In some embodiments, a plurality of through holes 421 are disposed inside the plurality of support blocks 430 , and one end of the plurality of through holes 421 extends to the surface of the second support layer 420 .

[0035] With such arrangement, heat is inevitably generated during the operation of the wires because the conductors have resistance. The double-layer structure of the support assembly 400 is not conducive to heat dissipation. Therefore, one end of the multiple through holes 421 arranged inside the support block 430 extends to the outer end of the second support layer 420. At this time, the through holes 421 can be used to accelerate heat dissipation and reduce failures or safety accidents caused by overheating of the equipment.

[0036] Please also read Figure 1 and Figure 3 In some embodiments, a plurality of elastic strips 500 are disposed on a side of the second supporting layer 420 away from the supporting block 430 , and the elastic strips 500 are arrayed on the surface of the second supporting layer 420 .

[0037] In this way, when the external extrusion force and tensile force are applied to the wire by the multiple elastic strips 500 disposed on the surface of the second support layer 420, the elastic strips 500 are squeezed to buffer and dissipate energy, absorb external vibration, extrusion and impact, and prevent the conductor core 100 from being deformed after being squeezed, thereby improving the stability of the wire. When the external extrusion force and tensile force are eliminated, the multiple elastic strips 500 can return to a normal state.

[0038] See also Figure 1 and Figure 3 In some embodiments, a protective layer 600 is provided at the outer end of the elastic strip 500 .

[0039] In this way, the outer side of the elastic strip 500 is provided with a wire protection layer 600, which can provide protection for the wire body during installation and use, for example, during installation and threading, and during use when heating. It protects the wire, provides insulation, prevents electromagnetic interference, enhances mechanical strength and corrosion resistance, and improves conductivity and heat dissipation.

[0040] Please also read Figure 1 and Figure 3 In some embodiments, a filling layer 510 is provided in the gap formed between the protective layer 600, the second supporting layer 420 and the plurality of elastic strips 500, and the filling layer 510 may be filled with a rubber material such as polyvinyl chloride, polyethylene or EPDM rubber.

[0041] In this way, the filling layer 510 is arranged between the protective layer 600 and the second supporting layer 420. When the wire is used, the filling layer 510 can effectively protect the inside of the cable from being squeezed and worn, and protect the normal service life of the wire. In addition, the filling layer 510 can also play a buffering role. When the protective layer 600 is squeezed, it can be transmitted to the filling layer 510. The filling layer 510 can absorb external vibration and impact force, improve the durability and impact resistance of the wire, and this filling layer 510 can make the wire shape more rounded, the surface is smooth and flat, and it is more convenient for users to thread the wire. In addition, the filling layer 510 makes the conductor core 100 more centered and uniform, which can improve the capacitance performance and anti-electromagnetic interference ability of the wire.

[0042] See also Figure 3 In some embodiments, the protective layer 600 is made of polyethylene and is tightly connected to the filling layer 510 .

[0043] In this way, the wire protective layer 600 made of polyethylene material is particularly excellent in corrosion resistance, high voltage resistance, wear resistance, aging resistance, and flame retardancy. It also has good insulation and can withstand the impact of high voltage electricity. When the user pulls the wire through the wire tube, the surface of the protective layer 600 is smooth and not easily affected by physical attacks such as scratches and wear. The protective layer 600 made of polyethylene material also has a waterproof effect. Its excellent characteristics can be used in different environments, which improves the practicality and versatility of the wire.

[0044] Please also read Figure 1 and Figure 3 In some embodiments, the conductor core 100 is formed by twisting a plurality of oxygen-free coppers 110 .

[0045] Such a setting can increase the service life of the wire. Oxygen-free copper 110 has excellent electrical conductivity, good corrosion resistance, excellent oxidation resistance and good processing performance. It can adapt to different electrical requirements and specifications. The quality of the conductor 100 is stable and reliable.

[0046] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
